Lost activation key

Hi guys,
I'm using Parallels desktop 15, I recently bought a new computer and I can't complete the installation because I can no longer find my activation key. The registered mail is grkmaksoy@gmail.com.

 

Kindly log in with your email grkmaksoy@gmail.com at Login - Parallels My Account and get your Parallels license key. Kindly check this link - Parallels Desktop and macOS compatibility to know the Parallels version compatibility with your current/new Mac OS version. Thanks.
